-is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials. The tester provides certain flow rate of bacterial aerosol. The operator can measure the number of colony forming units passing through the medical face mask material, which is clamped between a six-stage Anderson cascade impactor and an aerosol chamber, expressed as a percentage of the number of colony forming units present in the challenge aerosol.naKTextile Testing Instruments, Testing Equipment Manufacturer
